I think the probpem is that tthere are too many parents out there that tdont know WHEN to let their child just be a child. Instead too many parents reward their child when their child does childish things everywhere and anywhere when instead thes epareents should only be allowing their child to do childish things at an open space that is made to allowing children to do this type of experimentation like a playdium or a park or a gymnastics practice or a forest or jungle gym.... NOT in a restaurant.
I remmember having this one talk with a kindergarten teacher and theteacher was calm as a tranquilized cucumber despite seeing kids flyingn all oover the class room. SHe basically said that since children aree born not knowinng the physics or the 'rules' of ouur society, a society with rules that were crafted by adults , its basically like the children were born into a video game in 'sandbox mode'. The kids are just trying to unerstand what are ethe limits of, the rules, their bodies, or of the limitss of the physics of this world are at all times. The kids are basically 'testing EVERYTHING' all the time.
And now take that example of the kid running across the restaurant table and the parents saying 'Aww'. The parents in that situation were correct in letting their child 'test' out what it was running accross, but the parents were wrong in allowing. the child to conduct that test in the miiddle of the restaurant on a table. Had those parents taken their kiids first out to the playground to 'test' out what running on the 'tables' at the playground was slike and to burn off their energy then the child probablt wouldnt have had ran across that table. If that child had slipped on something oily or watery on the table and gotten injured ...weell.....
